upon stitchdown shoes.

By the term stitchdown shoe is meant, of course, that type of shoe inwhich the marginal portion of the upper is outturned and secured to asole the margin of which projects beyond the last bottom.

lV'hile the practice of differentmanufacturers varies in detail,stitchdown shoes may be considered generally as of three kinds, namely,single-sole, two- In the single-sole shoe, the margins of the upper, andlining, it any, are turned outwardly and secured to the margin of asingle extension sole. In the two-sole shoe, the margins of the upperand lining are turned outwardly and secured to a thin extension sole,the upper and extension sole being then secured to a second extensionsole, which is the outsole. In the threesole shoe, the first sole is aninsole which does not extend beyond the last bottom and is assembledonthe last with the upper; the lining is lasted inwardly over the bottomof the insole; a middle sole or first extension sole is then applied tothe last and the outturned upper is secured to the margin of theextension sole; and an outsole of the size of the entension sole is thenapplied to the shoe and secured to the upper and middle sole. In all ofthese shoes a welt strip is usually applied to the exposed surface ofthe out-turned margin of the upper and secured by means, usuallystitches, which go through the upper and single sole or through theupper and outsole it there is more than one sole. It is also usual toinsert a toe box and counter bet son the upper and lining at the toe andheel respectively, which are treated as parts of the upper materials.The toe box is frequently of material which can be softened prior to thelasting operation and contains cementitious material which, upon harden-1929. Serial No. 371,493.

ing after lasting, will hold, the upperin lasted position to theprojecting margin of the sole. Thermoplastic box toe material isextensively usedin this work and is effective, after cooling,temporarily to hold the lasted upper materials in lasted position untilthey are permanently secured.

In lasting the toe portions of stitchdown shoes of whatever type, it isparticularly desirable not only that the upper-materials be shaped overthe toe and into the angle between the side of the last and theprojecting margin of the sole, but that theupper at the angle be tuckedunder the edge of the last or insole so that a definite crease will beformed into which the edge of the welt strip may be forced and which inthe finished shoe will give an appearance similar to that of the weltcrease of a welt shoe.

An important object of this invention is to provide a machine by the useof which such a welt crease may consistently and uniformly be obtainedin stitchdown work.

Other objects of the invention are to provide improved means foreffecting the ten sioning of the upper materials in conjunctionwith theworking of them into lasted position, to insure that the shoe will beproperly positioned and maintained against displacement during the uppershaping operation and, without sacrificing any of the advantages ofprior machines for this work such as that disclosed in applicationSerial No. 244,230, filed January 3, 1928 in the name of Rene E.Duplessis, to provide a machine which will be rapid and effective inoperation and which will be more nearly automatic than prior machinesfor this work. 4

With these and other objects in view, the organization'oi theillustrated machine comprises a pair of end embracing Wipers constructedand arranged for advancing and closing movements and a shoe bottom restor support located below the wipers and of sufficient extent to supportthe forepart of a shoe bottom including the margin of the sole of astitchdown shoe which extends beyond the last bottom, together withpower-operated means for effecting relative movement of the wipers andsupport heighwise of the shoe to eiiect the operation of working theupper over the end of the last and against the projecting margin of thesole. As illustrated, the wipers are arranged to be manually adjusted toadapt them .to embrace the toes of shoes of different sizes andpower-operated mean-s is provided to impart to the wipers apredetermined advancing and closing movement to force the lasted uppermaterials under the edge of the last bottom, or under the insole in workin which the shoe is provided with an insole, said predeterminedmovement being timed to occur after such relative heightwise movementbetween the support and the wipers has been effected that the edge ofthe wipers is in a plane slightly below the edge of the last bottom. Asillustrated also, the predetermined advancing and closing movements ofthe wipers are effected positively and these movements are adjustable sothat the depth of the crease formed in the upper under the shoe bottommay be varied.

In the illustrated machine, furthermore, novel means is provided foreffectively tensioning thetoe portion of the upper during the operationof the wipers in shaping the upper to the last, such means preferablyacting at the cornersof the toe and at the sides of the toe. Asillustrated, separate clamps at the corners and sides of the toe areprovided,

which clamps are operated during the relative heightwise movement. ofthe wipers and support to elamp the margin of the upper against thelower surface of the wipers, the upper being progressively withdrawnfrom between the clamps and wipers during said relative heightwisemovement.

In order that the clamps may not interfere with the projecting margin ofthe sole and withthe pressing of the upper by the wipers against .theprojecting margin of the sole, means is provided in the illustratedmachine for withdrawing the clamps from operative position at that timeduring said relative heightwise movement when the wipers and the soleare in proximity to each other, the clamps at the corners of the toebeing moved bodily lengthwise of the shoe and the clamps at the sides ofthe toe being swung outwardly away from the shoe to an inoperativeposition.

In order that the relative heightwise movement of the wipers and shoesupport may be fully effective to work the upper into lasted positionand to prevent movement of the shoe and last in response to theadvancing movement of the wipers to form the crease, improved means isprovided to hold the last against endwise rearward movement. Asillustrated, a member or abutment is provided for engaging the rear endof the shoe and the abutment is operated in conjunction with therelative heightwise movement of the wipers to forceit against the shoe.This force is preferably applied yieldingly and provision is made forsetting the position of the abutment, with respect to the means by whichforce is applied to it, to adapt the machine to handle shoes of variouslengths and to insure that substantially the same pressure will beapplied to shoes of various sizes irrespective of their length. hen theshoe is released from the illustrated machine, the abutment isautomatically withdrawn from the shoe a sufficient distance to permitconvenient removal of the shoe and provision is made to insure that theabutment, when its position is changed for another length of shoe, willbe so set with respect to the new length of shoe that this distancebetween the shoe and upper will always obtain after the shoe is releasedby the machine. The abutment is preferably arranged to be carried by thesole support and to be adjustable with respect thereto in accordancewith the spring and with the swing of the last without affectingtheconnection by which the abutment is 0perated to apply endwisepressure to the shoe.

These and other features of the invention, including various novelconstructions and arrangements of parts, will appear more fully from thefollowing detailed description vhen read in connection with theaccompanying drawings and will be pointed out in the appended claims.

block to the gear.

The illustrated machine for shaping'uppers over the end portions ofstitchdown shoes, and particularly the toe ends of such shoes, comprisesa base or frame in which is mounted a main shaft 12. On the shaft 12 aremounted a gear 14 and a cam block 16, there being between the gear 1%and the cam block 16 a suitable form of half-revolution and there beingon the right-hand side of the machine a cam block similar to the camblock .16 for imparting movements to the op erating instrumentalities onthe right-hand side of the machine. The mechanism at the left-hand sideof the machine will be particularly described, it being understood thatthe mechanism at the right-hand side of the machine is substantially aduplicate of that on the other side, except for reversal of parts, andis arranged for operation on a shoe for the opposite foot, for example aright shoe. As best shown in Fig. l, a stop projection 20 on the clutchbetween the gear 14 and the cam block 16 engages a stop arm 22, said armbeing pivoted at 2 1- and having a forward projection carrying a pin 26which is slabbed off on its front side. An upright bar 28 has anelongated notch 30 in its upoer end engaging thepin 26 and at its lowerend is pivoted at 32 to a treadle 3 1. The length of the notch 30 issuch that lost motion between the bar 28 and the pin 26 is permittedduring the preliminary depression of the treadle, the notch 80 engagingthe pin 26 and lifting the arm 22 from the projection 20 to permitsetting of the clutch only during the final depression. After themachine starts. the bar 28 is pushed forwardly by a suitable formationonthe cam block 16 to free the notch 30 from the pin 26, allowing the stoparm 22 to drop back intopositi on to stop the machine again after thecam block 16 has made half a revolution.

The clutch and driving mechanism above briefly described may besubstantially similar to that disclosed in United States Letters PatentNo. 1,674,085, granted June 19, 1928, on application of Ballard andSeely, to which reference may be had for further explanation of thispart of the machine.

A bar 36 is forked at its rear end to embrace the shaft 12 upon which itis guided. Pivoted at 38 on the inner sideof the bar 36 is a roll whichengages a cam track 40 in the cam block 16 by which the bar is movedlengthwise. At its forward end the bar is pivoted at 42 to the joint ofa toggle one link la-of which is pivoted at 16 to a rod 48 upon theupper portion of. which is threaded a nut 50. The rod 48 extends freelyinto a hole in the top ofa plunger '52 which is mounted forreciprocation in a cylindrical member 5 1, the upward movement of theplunger being limited by a screw 56 extendinginto a slot in the side ofthe plunger 52. Beneath the plunger is a spring 58 which rests on asupport mounted for adjustment to vary the tension of the springby'turning a conveniently arranged handle 59, as explained in theabove-mentioned patent. The other link 60 of the toggle ispivoted to ablock 62 (Fig. 4) mounted in a slot 64; in the lower end of alongitudinally movable shaft 66. To confine the block 62 in the slot 6 1a strap 68 is passed around the end of the post 66 and secured theretoby a bolt 70. Between the upper end of the block 62 and the end of theslot 64 is a space to permit the shaft 66 to be adjusted relatively tothe block 62, as will be explained. The shaft 66 is-guided for movementin the frame 10 of the machine in a direction inclined upwardly andrearwardly with respect to the machine and at its upper end has areduced portion 74 on which is pinned a block 76. On the top of theblock 76, which is horizontal, a sole supporting plate 78 is mounted bydowel pins one of which is shown at 80. On the lower end of the block 76is a screw 81 which engages a boss on the frame and adjustablydetermines the heightwise position of the block 76 and shoe support 78,such adjustment being permitted by the portion of the slot 6 1 above theblock 62. Thus the normal position, heightwise of the shoe, of the plate78 may be varied for different thicknesses of soles by turning the screw81. The plate 78 corresponds substantially in size and shape to theforepart of a stitchdown shoe sole includin themarginal extensionthereof, and, in order to take care of large variations in shoe sizes,the plate 78 may be lifted off and a larger or smaller plate substitutedto correspond to the size of shoe being treated.

In the forward portion of the block 76 is mounted a pin 82 which is heldin place by a draw-boltSl. The draw-bolt 84, however, need not be set uptightly enough to prevent turning of the pin 82 but only sufficiently tohold it frictionally against turning 'movement. To the pin 82 is pivotedat 86 a member 88 which can be swung laterally on the pin to correspondto the swing of the last. Through a depending portion 89 of the member88 is threadeda screw 90 bearing against the block 76 and provided witha hand-wheel 92 which may be turned to vary the angular relation in avertical plane of the member 88 to the sole support 78, this adjustmentbeing to take care of the spring of the last. The member 88 (Fig. 5) ischanneled at 94 to re ceive a sliding member 96 the upper surface ofwhich is formed with rack teeth98. The

slide 96 is channeled on its under side to receive a compression spring100 which bears at its inner end against the member 88 and at its outerend against the slide 96, the spring tending to hold the slide 96outwardly against a suitable stop 102.

Arranged to slide on the top of the member 88 is a carriage 104, saidcarriage having a portion which extends into the channel 94 and isprovided with ribs 106 which engage corresponding grooves formed in theupper portions of the side walls of the channel 94, the lower'face ofthe carriage being arranged just above the surface of the rack teeth 98and in sliding relation thereto. A plunger 108 is mounted in thecarriage 104 for limited movement perpendicularly to the rack bar 98 andhas teeth on its lower surface to engage the rack teeth 98 and lock thecarriage 104 to the slide 96. The plunger 108 is held depressed by acompression spring 110 the upper portion of which surrounds the stem ofa headed pin 112 the head of which frictionally engages a stem 114arranged for sliding movement through the carriage longitudinally of theshoe. On the inner end of the stem 114 is pivoted at 116 an abutment 118which is adapted to engage the rear end of the shoe, the abutment 118preferably having a cover 120 of yielding material to prevent marring ofthe shoe upper and also having, as shown in Fig. 3, projecting portions122 which prevent lateral movement of the rear end of the shoe withrespect to the abutment 118. Inward movement of the stem 114 withrespect to the carriage 104 is limited by a lug 124 on the stem whichengages the carriage, and the stem is frictionally held from accidentaldisplacement by friction of the headed pin 112 thereon due to thepressure of the spring 110. In order that the position of the carriage104 with respect to the rack bar 98 may be changed to accommodatedifferent lengths of shoes, the plunger 108 may be lifted against thetension of the spring 110 to disengage its teeth from the rack teeth 98by a hand-piece 126 which at its lower end is secured by a pin 128 tothe plunger and is guided for vertical movement with respect to thecarriage by a headed stud 130 engaging suitable vertical guideways inthe carriage 104, a slot 132 in the carriage permitting verticalmovement of the pin 128. hen the stem 114 is in its rearward position,it lies over the hand-piece 126 so that the handpiece cannot be liftedto release the teeth of the plunger 108 from the rack bar 98. If,however, the stem 114 is pushed inwardly of the machine, the hand-piece126 is free to be lifted and the carriage 104 can be placed in anyposition along the rack teeth 98. In order to locate the abutment 118 inthe proper position for operation upon a shoe of given length, the stem114 is pushed forward, the hand-piece 126 lifted, and the carriage 104moved outwardly a suflicient distance to admltthe shoe, which is thenplaced in the machine as shown in Fig. 4. The carriage 104 is then movedinwardly toward the shoe untilto the shoe at a point heightwise of theshoe .50

which is near the plane of the sole. WVhen the carriage 96 is allowed tobe moved back by its spring 100, there will, of course, be at the rearof the shoe between the shoe and the abutment a space equal to theamount of relative movement between the abutment and the carriage sothat the shoe can be easily removed from the machine, but, since thecarriage 104 cannot be reset for a different length of shoe withoutfirst pushing the stem 114 inwardly to release the handles 126, it isassured that the space between the shoe and abutment will always obtainwhen the shoe is released and that the pressure applied to the shoe bythe abutment will not be excessive.

For moving the slide 96 to operate the abutment as described, a pulley136 is mounted on a stud 138 fixed to the slide 96 and occupying a slot140 in the member 88. The bight of a cable 142 is placed upon the pulley136, each of the two runs of the cable being passed over an idle pulley144 mounted on the depending portion 89 of the member 88 near its pivot86 and the two ends of the cable being held in a clamp 146 whichcomprises two similar plates grooved to receive the cable and heldtogether by a bolt 148. The clamp 146 is connected to an arm 150 of anangle lever by means of a yieldingly extensible connection which, asillustrated, comprises two identical U-shaped members 152 and 154 whichhave their ends reversely bent to form hooks. The members 152 and 154are passed in opposite directions through a compression spring 156, theloop of one being engaged by the bolt 148 and the loopof the other beingengaged by a pin 158 passing through the end of the arm 150, which isbifurcated. Also connected to the pin 158 is a treadle rod 160 whichpasses through the outer portion of the treadle lever 34 (Fig. 1) andhas thereon between the treadle and a nut 162 on the end of the rod acompression spring 164 which is still enough to overcome the spring 100.Consequently, when the treadle is depressed the slide 96 will be movedtoward the shoe through the spring 164. The arm 150 above mentioned ispart of an angle lever the other arm 166 of which (Fig. 4) is pivoted bya pin 168 to the shaft 66. A link theinitlal depression of the treadledescribed,

the angle lever 150, 166 will turn on the pin 168 as a fulcrum, the pin176 then moving downwardly in the slots 17 4 and the carriage 104 willbe moved toward the shoe to take up the lost motion between it and theabutment 118, the portion of the arm 166 at the rear of the pin 168 ofcoursemoving upwardly.

Toeach side of the rear end of the arm 166 is pivoted at 178a sleeve 180through which passes a rod 182 having stop nuts 184 on its lower end. Oneach rod 182 is threaded a nut 186 forming an adjustable stop betweenwhich and the sleeve 180 is a compression spring 188. The upper ends ofthe rods 182, 182 pass through a horseshoe-shaped plate 190 (Fig. 8) andeach rod is threaded into an upright member 192 to which is so cured at-194 a clamp 196 having a laterally extending portion directed toward theshoe and arranged to be under the projecting margin of the upper and tobe over the projecting margin of the sole. The clamps 196, 196 arearranged at the corners of the toe and by upward movement of the members192 are operated to clamp the outwardly extending margin of the shoeupper at the corners of the toe against the lower surface of toeembracing wipers 200,202 which, as shown in Figs. 4 and 8, embrace theshoe toe in a plane located above the shoe bottom. The lower position ofthe upper clamps is adjustable by means of a screw 204 threaded throughthe horseshoe-shaped plate 190 and engaginga flat surface on the frame10, the adjustment being such that the lateral projections of the clamps196 are just above the projecting margin of the sole. The members 192(Figs. 3 and 8) are guided on their'inner faces by fiat surfaces formedon projections 206 of the block 76 carrying the shoe support and ontheir outer faces are guided by rearwardly projecting portions 208 ofplates 210 fixedly secured to opposite sides of the block -7 6. Thisconstruction enables the members 192 to be moved toward and from theshoe lengthwise thereof to carry the corner clamps 196, 196 intoand outof upper clamping position, such movement being permitted, of course, byswinging movement of the rods 182 about their pivot 178- to the leverarm 166. Each of the plates 210 is provided with two ears 212 2) inwhich is mounted a vertical stem 214 (Fig. 8) the lower end of whichrests ou the horseshoe-shaped plate 190 and the upper end of which hasan offset portion2-16 to which a side clamp 218 is secured at 220. Byturning movement of the stems 214, therefore, the clamps 218 may beswung laterally of the shoe toe into and out of position to clamp theupper against the wipers In order to swing the side clamps 218, 218outwardly of the shoe and to move the corner clamps 196, 196 bodilylengthwise of the shoe, the following mechanism is provided: On

each of the stems 214 is an arm 222 to which is pivoted at 224 a block225 having ears 226 to which is pivoted at 227 a link comprising twomembers 228, 229 which are threaded together so that lengthwiseadjustment of the link may be effected. The rear end ofthe link 228, 229is pivoted at 230 to a member 232 fixed to a horizontalrod'234, this rodpassing through holes formed'inth'e members 192 which carry the cornerclamps" 196. The central portion of the rod 234 passes througha yoke 236intowhich is threaded a link 238 i (Fig. 4) the rear end of the linkbeing pivoted at 240 to a lever 242 fulcrumedat 244 on the machine frameand pivotally connected at its lower end to the toggle actuating bar 86.In order that the rectilinear movement of the bar 36 may be utilized toimpart move-- ment to the lever 242, a forked member 246 is bivoted toan ear 248 on the bar 36- and has a stem 250 which slides freely in ahole bored lengthwise of the lever 242. By the mechanism described itwill be apparent that forward movement of the bar 36 will move thecorner clamps 196 away fromthe shoe and will swing the side clamps 218outwardly about the stems 214 away from the sides of the shoe, theclamps being thus moved outof position to clamp the upper against thewipers and their lateral extensions being consequently removed fromposition over the projecting margin of the sole so that the wipers andthe shoe support may be relatively operated to press the outturnedmargin of the upper and the projecting margin of the sole together. 1

The wipers 200, 202 (Fig. 3) which embrace the end of the shoe are'each.detachably secured at251 to a wiper carrier 252.

Each wiper carrier is provided with two arcuate'slots 254 which engagerolls 256 mounted on fixed axes in the wiper head 258', the slots 254being s0 formed and arranged that when the wiper carriers are movedtoward. the

shoe the wipers 200,202 will be advanced and cover-plate 261 and thehead 258 which ex tend inwardly over the ends of the wipers and sustainthem against upward pressure.

Two separate means are provided for effecting advancing and closingmovementsof the wipers, one being a manually effectedad j ustment forthe purpose of setting the wipers .130

so that they will correspond to the shape and size of the toe of ashoebeing lasted and the other being a power-effected movement ofpredetermined extent to cause the wipers to tuck the fold of theoutturned upper under the edge of the last. Each wiper carrier 252 isconnected at 262 to a link 264 the rear ends of the links 264 beingpivoted at 266 to a cross-bar 268 having a rearwardly extending threadedstem 270. The stem 270 is threaded into a sleeve 272 which is mountedfor rotating movement in a boss 274 formed on tire wiper head 258 and isheld from rearward movement by a flange 276. The rear end of the sleeve272 is formed as a threaded stem 278 on which is threaded a hand-wheel280, the hand-wheel being normally fixed to the stem by means of aset-nut 282. Between the ,hand-wheel and the boss 274 is a compressionspring 284. It will be seen that by turning the hand-wheel 280 thesleeve 272 may be turned and the bar 268 moved forwardly or rearwardlyto adjust the wiper carriers and hence the setting of the wipers 200,202;

"that is, the extent to which they are initial- 1y advanced and closed,or retracted and opened, may be varied. The power-effected advancing andclosing movement of the wipers is caused by pressure applied to the rearend of the stem 278 by an adjustable screw 286 threaded through theupper end of a lever 288 (Fig. 4) fulcrumed at 244 and having a roll 290on its depending arm arranged to engage an edge cam 292 on the cam block;16. The screw 286 affords means for varying the effective upper tuckingor crease forming movement of the wipers. The timing oft-he cam 292, asshown in Fig. 9, is such that the wipers are advanced and closed.positively a predetermined amount after initial upward pressure has beenapplied to the work support 78 by the cam 40, acting through the toggle44, 60,-to press the outturned margin of the upper and the projectingmargin of the "sole against'the wipers and prior to the final pressureapplied by the cam 40 to the work support.

In order to clamp the upper to the last in.

the vicinity of the tip line to prevent undue movement of the upperrelatively to the last by the tension applied to the upper. such asmight result in forward bowing of the tip seam, a toe clamp 294 isprovided, the clamp being preferably padded with yielding material 296and provided with a cover 298 of a washer engaging the sleeve 302.Rotation of the stemis prevented by a screw 312having a flattened endengaging a groove in the stem 300. The position of the clamp 294longitudinally of the shoe may be varied by loosening the bolt 304,turning the sleeve 302 on the bolt as an axis and tightening the bolt.In the drawings the machine is illustrated as operating upon astitchdown shoe which, when completed, will have three soles. It is tobe understood, however, that the machine is equally well adapted foroperating upon shoes of any of the three kinds hereinbefore referred toor variations thereof. At the time when the toe lasting operation isperformed, the shoe comprises an insole a and a middle or firstextension sole 6 secured to a last 0 on which are assembled an upper dand lining 0, the lining 6 having been wiped, in and secured to theinsole by cement prior to the attachment to the last of the middle soleb.

It is also a usual practice in some work to pull over both the upper andthe lining and secure them temporarily to the insole by partially driventacks before the middle sole is applied, the shoe being allowed toremain in this condition until the upper has set to the last. The upperis then released by pulling the tacks, the lining secured to the in-:sole and the middle sole applied, the shoe being in this condition whenit comes to the operator of the illustrated machine. It is also usual toinsert a heated thermoplastic toe box f between the upperand lining justprior to the introduction of a shoe into the machine.

In the operation of the machine the op erato'rwill slide forwardly thestem 114 of the abutment 118 to release the hand-piece 126, will raisethe plunger 108 and move the carriage 104 rearwardly far enough to admitthe shoe, that is, of course, unless the carriage is alread in thatposition. The forepart of the shoe bottom is then placed upon thesupport 78 with the end. of the shoe against the wipers 200, 202, whichare adjusted if neces- T sary by means of the hand-wheel 280 to ad-Vance and close the wipers or to retract and open them until they fitthe size of toe being operated upon. The carriage 104 will now be Ireleased by lifting the hand-piece 126 and moved toward the shoe untilthe abutment 118 engages the shoe.

when it is raised, the operator cannotmove the carriage toward the shoefar enough to take up the lost motion provided between the stem 114 andthe carriage. If the operator the shoe as it should, he will swing themem- Since the stem 114 of the abutment engages the hand-piece v126 her88 on the pin 82 against the friction of the draw-bolt until theabutment is properly located so that the rear end of the shoe willengage between the projections 122 on the abutment. This lateralswinging move J of the cable 142 to lengthen as the other run shortens.Upon contact of the abutment with the shoe, the hand-piece 126 isreleased and the carriage 124 becomes locked to the slide 96 by theaction of the spring 110 on the plunger 108. e

If the operator finds that the carriage 104 is not adjusted heightwisein accordance with the spring of the last properly to engage the rearend of the sole while tile forepart is in flat engagement with thesupport 7 8, he will operate the hand-wheel 92 to effect suchadjustments, the member 88 then turning on its pivot 86 to the pin 82.This movement, however, does not materially affect the tension of thecable 142 because the idle pulleys 144 are pivoted near the pivot 86 ofthe mem-,

ber 88.

To move the slide 96 and the carriage 104 1 toward the shoe, theoperator depresses the treadle 24 which acts through the rod 160 and thecable 142 to move the slide 96 and the carriage toward the shoe. Duringthis movement the carriage 104 will move relatively to the abutment totake up the lost motion between the abutment and the carriage and tobring the projection 184 into position to engage the abutment 118 at apoint heightwise of the shoe which is below the center of the rear endof the last, pressure at this point being effective to hold the shoeagainst the wipers at the toe. During this movement of the carriage 104the lever 150, 166 has been turning on the pin 168 as av fulcrum whilethe pin 17 6 has moved downwardly in the slots 17 4 of the link 170.This movement of the angle lever, acting through the springs 188, haslifted the clamps 196, 218 sufliciently to engage the upper and press itlightly against the lower face of the wipers 200, 202. If the operatorfinds, upon inspection of the shoe, that the upper materials have notbeen properly positioned between the wipers and the clamps, or wishes tochange the adjustment of the machine for any reason, the treadle may bereleased and the operation repeated. The manual operation performed bythe treadle as described puts very little burden upon the operator sincein this operation only the tension of the light spring 100 has to beovercome in moving the carriage 104 and the clamps 196,218 raised intoposition toengage the upperwithout applying substantial pressure to theclamps through the springs 188 or to the abutment 118 through the spring152. lVhen the parts have been moved by the treadle into thesepositions, however, the added resistance of the springs 188 to movementof the treadle causes the spring 164 to yield slightly and the clutchto'be tripped since the lift the stop arm 22 and trip initial movementof the treadle 34 has taken up the lost motion provided by the notch 30,so that the final depression of the treadle will the clutch, powerrotation of the cam block 16 then taking place. During the poweroperation-of the machine, the bar 36 will be moved longitudinallyforwardy of the machine by the action of the cam track 40, causing thetoggle 44, to be straightened. As the toggle is straightened, the space7 2 above the block 62 will be first taken up and then the shaft 66 willbegin to move upwardly. The pin 17 6, having been brought by theoperation of the treadle to the bottom of the slot 174, now becomes thefulcrum of the angle lever 150, 166, and, as the shaft 66 carrying theshoe supports 78, 104 moves upwardly under power. to effect relativeheightwise Wiping movement between the shoe and the wipers 200, 202, thetension of the springs 188 will be rapidly increased since the rear endof the lever 166 moves faster than its point of connection 168 to theshaft 66 to cause the upper to be clamped against the wipers more andmore firmly as the wiping operation progresses. At the same time the arm150 has moved downwardly about the pin'176 as a center to cause theabutment 118 to be pressed yieldingly against the rear end of the shoethrough the spring 156.

The faces of the. clamps 196, 218 which engage the upper are preferablytransversely undulated or corrugated, asshown in Fig. 8, to providesuflicient friction between the clamps and the wipers so that the upperwill not slip until the desired tension has been applied thereto and yetwill not hold the upper so that it cannot slip or to such an extent thatthere is danger of its being damaged. The side clamps 218 aresubstantially opposite the outer ends of the wipers and the wipers arerelatively long, so that the tension produced by the clamps 218 willcause the upper to be drawn down tightly to the last just at the rear ofthe tip line. The clamps 196, be-

- ing placed at the corners of the toe, effect longitudinal tensioningof the upper at each side of the longitudinal median line along whichtheupper was previously stretched in the pulling-over operation, if thatoperation was employed, and effect tensioning, of those portions of thetoe'of the upper which re ceive less tension during the pulling-overoperation, that is, the portions which, when theshoe was in pulled overcondition, constituted the ears or folds of the upper formed in thatoperation at the corners of the toe.

During the upwardmovement of the shoe support 78 the upper is clamped tothe last in the vicinity of the tip line by upward pressure of the shoeagainst the yielding abutment 294. This clamping of the upper to thelast during the wiping operation prevents the tip wvardly and upwardlyso that during the upward movement of the shaft there is a;

component of movement of the shoe support and shoe toward the wipers toenhance their 4 wiping action. During the early part of the wipingoperation, the lateral extensions of the clamps 196, 218 are positionedover the projecting margin of the middle sole 6 with their ends close tothe last and hence must be a moved outwardly of the shoe to permit theprojecting margin of the sole to be pressed against the outturned marginof the upper. This is effected by the described movement of the bar 36which operates the lever 242 to retract the corner clamps 196 and toswing the side clamps 218 outwardly so that by the time the first riseof the shoe-support-pressure-cam 40 is effective, as shown in Fig. 6, toapply preliminary pressure to the sole and upper flange between thesupport 7 8 and the wipers 200, 202, the clamps will be suilicientlywithdrawn to clear the margin of the sole. During the movement of theclamps outwardly of the shoe, less and less of the area of theirclamping faces is in engagement with the upper-butat the same time theupward pressure on the clamps progressively increases so that theeffective clamping action of the clamps is substantially constant duringthat portion of the upward movement of the suplustrated in Fig. 7, theupper is tucked at the angle between the side of the last and theprojecting margin of the sole under the last bottom and against the edgeface of the insole F). Since the advancing and closing movements of thewipers are positive and predetermined and the. shoe is held againstrearward endwise movement by the abutment 118 as well as by the toeclamp 294, this creasing of the upper or carrying of the fold of theupper under the last bottom will be consistently and uniformly effectedindependently of the operator. If, for any reason such as faulty adustment of the mach ne, the wipers should engage the side of the as insea 0 ){ISSlD in e r l,- l t t d f j g r d r the last bo tom during theirpredetermined power operation, the shoe can be forced rearwardly againstthe tension of the abutment spring 156: and breakage of the machine willconsequently be avoided. hen, in the case of a three-sole shoe,asillustrated, the wipers are operated against the edge of the insole, theinsole will yield sufiiciently in response to the positive poweroperation of the wipers to permit the upper to be carried under the lastbottom to the required extent. Of course, under conditions where themargin of the sole is beveled or shoulder channeled, or where the marginof the last bottom is beveled, the operation of the machine will beequally as effective as under the more diflicult' conditions described.v

While the wipers are held in by the wiper cam 292, the second rise ofthe shoe-supportpressure-cam operates the toggle 44, to apply final andmaximum pressure to the shoe support to ress the outturned flange of theupper and t 1e projecting margin of the sole more firmly against thewipers and to set the crease formed in the upper The cam block 16 havingnow made a half revoution, the machine stops with the shoe held underpressure. he amount of upward pressure of the shoe support is, ofcourse, determinod by the amount of compression of the spring 58, andthe point in the cycle of the machine when the spring is brought intoaction may be varied to suitdifferent conditions of work by adjustmentof the nut 50 on the plunger 48, the initial tension of the spring 58being controlled by turning the handle 59.

The shoe remains under pressure until the operator has similarly treatedanother shoe, for example a shoe for the opposite foot, by the mechanismat the right-hand side of the machine. su 'iposing a thermoplastic toebox to have been inserted between the upper and lining prior to theplacing of the shoe in the machine, the toe boxwill, of course, havebeen shaped to the last with the upper and its margin laid against theprojecting margin of the sole. While the shoe remains in the machineunder pressure, the hot cementing materials with which the toe box issaturated have time to cool and the pressure exerted causes some of thematerials to be squeezed out of the toe box and to cause adhesion of thetoe box to the extension sole and to the upper so that when the shoe,after cooling, is released from the machine, the materials remain inlasted condition and the shoe is ready for the usual subsequentoperations of attaching the upper to the extension sole by stitches orstaples and for the application of an outsole and welt, the latter beingplaced snugly in the crease provided by the action of the wipers aboutthe toe of the shoe, and the welt, upper, middle sole and outsole beingsecured together by stitches.

In order to release the shoe the operator again depresses the. treadle34, whereupon the parts are restored to initial position, the abutment118 being pushed outwardly by the spring 100 acting on the slide 96 andtherefore opening up a space at the lot rear end of the shoe equal tothe amount of lost motion between the abutment 118 and the carriage 104.Thus ample space is provided for the removal of the shoe and for theroduction of another shoe of the same without any ad ustments beingmade. wt course if the next shoe to be placed in the machine issubstantially larger orbination of end embracing wipers constructed andarranged for advancing and closing movements, a shoe support adapted tosupport the projecting margin of a sole upon the last-Y 11 cans forefi'ectin relative movement of the wipers and the support heightwise ofthe shoe to shape the upper to the last, and. nea-ns operative to effectadvancing and closing movements of the wipers, said lastn med meansbeing constructed and arranged to initiate said advancing and closingmovements substantially at the termination of said relative heightwisemovement to force the upper in the angle between the side of the lastand the projecting margin of the sole under the last bottom while theoutturned margin of the upper lies against the projecting margin of thesole.
